Abstract
The utility model discloses a rotating shaft for a visual laryngoscope. The rotating shaft comprises a handle and a display screen seat, a connecting piece is fixed on the display screen seat, each of the handle and the connecting piece is provided with a through hole, the front end of the rotating shaft sequentially penetrates the through holes of the handle and the connecting piece to be tightly fixed through two nuts, and an end-surface bearing is arranged on the rotating shaft between the connecting piece and the nuts; concave and convex structures engaged with each other are arranged between the display screen seat and the connecting piece; the rotating shaft is a hollow shaft. By the arrangement, assembling and pre-tightening of the rotating shaft and relevant parts are convenient to adjust.
Description
Technical field
This utility model relates to a kind of armarium, relates in particular to a kind of rotating shaft for visible laryngoscope.
Background technology
The angle of the display screen of visible laryngoscope is adjusted from patient's different often needs according to doctor, and its handle was realized with being connected with rotating shaft of display screen component.
In prior art, conventional visible laryngoscope mostly is screw with the connection at rotating shaft two ends and fixes, due to the handle of visible laryngoscope and the space of display screen seat junction less, the mounting or dismounting that screw connects need specific purpose tool.
Utility model content
The purpose of this utility model is to provide a kind of dismounting and the rotating shaft for visible laryngoscope easy to adjust.
The purpose of this utility model is achieved through the following technical solutions:
Rotating shaft for visible laryngoscope of the present utility model, comprise handle, display screen seat, on described display screen seat, be fixed with brace, between described handle and described brace, by rotating shaft, be connected, the rear end of described rotating shaft is provided with flange, the front end of described rotating shaft is provided with nut, and the rotating shaft between described brace and described nut is provided with end face bearing.
The technical scheme being provided by above-mentioned this utility model can be found out, the rotating shaft for visible laryngoscope that this utility model embodiment provides, owing to being fixed with brace on display screen seat, between handle and brace, by rotating shaft, be connected, the rear end of rotating shaft is provided with flange, the front end of rotating shaft is provided with nut, and the rotating shaft between brace and nut is provided with end face bearing, easy accessibility, easy to adjust.
Accompanying drawing explanation
The structural representation of the rotating shaft for visible laryngoscope that Fig. 1 provides for this utility model embodiment;
Fig. 2 is brace and display screen seat connection diagram in this utility model embodiment;
Fig. 3 is this utility model embodiment shaft and handle connection diagram.
The specific embodiment
To be described in further detail this utility model embodiment below.
Rotating shaft for visible laryngoscope of the present utility model, its preferably the specific embodiment be:
Comprise handle, display screen seat, on described display screen seat, be fixed with brace, between described handle and described brace, by rotating shaft, be connected, the rear end of described rotating shaft is provided with flange, the front end of described rotating shaft is provided with nut, and the rotating shaft between described brace and described nut is provided with end face bearing.
On described handle and described brace, be respectively equipped with through hole, the front end of described rotating shaft is successively through the through hole on described handle and brace, and the front end of described rotating shaft is provided with two described nuts.
Between described display screen seat and described brace, be provided with the concaveconvex structure of mutual interlock.
Between described display screen seat and the concaveconvex structure of described brace, be provided with adhesive.
Described rotating shaft is hollow axle.
The rotating shaft for visible laryngoscope of utility model, only need connect rotating shaft handle, and display screen component and rotating shaft are inserted by specific concaveconvex structure, ease of assembly, and it is convenient that the assembling of rotating shaft and correlated parts, pretension regulate.
Specific embodiment:
As shown in Figure 1, comprise that handle 1, rotating shaft 2, brace 3, end face bearing 4, nut 5, nut 6, display screen seat 7 form, its shaft is hollow structure, and in order to passing through of cable, brace 3 can relatively rotate with rotating shaft 2.
Concrete rotating shaft and display screen seat syndeton are as shown in Figure 2, by brace, be connected with the concaveconvex structure on display screen seat, nut 5 is adjustable to suitable damping with nut 6, mutually tightening can be locking, make brace 3 and the rotation of rotating shaft 2 can remain on the angle needing, also limit relative displacement vertically between rotating shaft and handle and display screen seat.
Concrete rotating shaft and handle connecting structure as shown in Figure 3, by being connected with all directions on handle in rotating shaft, to limit rotating shaft and handle relatively moving radially.
Installation steps of the present utility model are:
Rotating shaft 2 is connected with handle 1, and all directions contact at two places puts in place, packs successively brace 3 into, sliding bearing 4, nut 5, nut 6, adjusting nut 5 and nut 6 positions can move axially by promote-side spherical bearing 4, obtain suitable damping, mutually tighten locking, now, the axial degree of freedom of brace 3 is defined, can only rotate along shaft centerline, at the concavo-convex place of display screen seat 7, be coated with the concavo-convex place that bonded adhesives is loaded to brace, bonded adhesives completes after solidifying.Display screen together with brace 3 only around the shaft centrage rotate and can rest on the position needing.
This utility model adopts rotary shaft hollow structure, and cable passes through, and the angle that doctor adjusts display screen can not cause that cable is wound around, and by the damping of nut capable of regulating rotating shaft, makes display screen can rest on the position needing.
The above; it is only the preferably specific embodiment of this utility model; but protection domain of the present utility model is not limited to this; anyly be familiar with those skilled in the art in the technical scope that this utility model discloses; the variation that can expect easily or replacement, within all should being encompassed in protection domain of the present utility model.Therefore, protection domain of the present utility model should be as the criterion with the protection domain of claims.
